I have been using PayPal buttons for years and have quite a number on our sales website. Recently I have noticed that when using Firefox I get "Things don't appear to be working at the moment. Please try again later." and this seems to be persistent. I am not doing anything special with the HTML code and simply attach it to an Add To Cart button on the site. Firefox which is my browser of choice is up to date and using Chrome things seem to work OK. Does anyone have an idea whether this is a Firefox problem or a PayPal problem?
